description
These 10-bit latches feature 3-state outputs
designed specifically for driving highly capacitive
or relatively low-impedance loads. They are
particularly suitable for implementing buffer
registers, I/O ports, bidirectional bus drivers, and
working registers.
The ten latches are transparent D-type latches.
The
SN74ALS841
and
SN74AS841A
have
noninverting data (D) inputs. The SN74ALS842
has inverting D inputs.
A buffered output-enable (OE) input places the ten
outputs in either a normal logic state (high or low
logic levels) or a high-impedance state. In the
high-impedance state, the outputs neither load
nor
drive
the
bus
lines
significantly.
The
high-impedance state and increased drive provide
the capability to drive bus lines without interface or
pullup components.
OE does not affect the internal operation of the latches. Previously stored data can be retained or new data can
be entered while the outputs are off.
The SN74ALS841, SN74AS841A, and SN74ALS842 are characterized for operation from 0
°C to 70°C.
PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of Texas Instruments
standard warranty. Production processing does not necessarily include
testing of all parameters.
